IMPROVED WASHING-MACHINE.

Specification forming part of Letters Patent No. 114,200, datedSeptember 13, 1864.

To all whom fit may concern:

Beit known that I, A. A. KENT, of Owatonna, in the county of Steele andState ofMinnesota, have invented a new and Improved Clothes-WashingMachine; and I do hereby declare that the following is a full, clear,and exact description thereof, which will enable those skilled in theart to malte and use the same, reference being had to the accompany.'

in which- Figure l is a side sectional view ot my invention, taken inthe line v x, Fig. 2; Fig. 2, a plan or top ofthe same, a part of therubber being in section.

Similar letters of reference indicate corresponding parts.

This invention relates to a new and improved clothes-washing machine ofthat class iu which an oscillating rubber and a stationary concave areused; audit consists in a novel manner of constructing the concave-toWit, with projections, covered with zinc, and arranged as hereinaftershown and described, and also in covering theprojections of thei rubberwith zinc, and employing metal bearings for the journals of the rubber,all being arranged as hereinafter set forth, whereby an f exceedinglydurable machine is obtained, and one which will not be liable to wear orinjure the clothes. l

A represents the suds-box, which is provided with a semicircular bottom,a, of zinc, and supported at any convenient heightl by a suitableframing, B. The sides b b of the suds-box are of wood7 and in the innersurface of each side there is made a simicireular groove, c, concentricwith and a short distance above the bottoni a. (See Fig. 1.)

C repn sents a concave, which is composed of alternate projectingV-shaped bars (I, and at strips or slats e, the bars and slats being ofwood, with their ends fitted in the grooves o. The bars d are coveredwith zinc,f, and the slats e are notched at each edge, as shown at g, toadmit ofthe suds passing freely through the concave.

D is a rubber, composed of two sides, h h, which form the greaterportion of a circle, and are connected by one or more cross-bars, i1',in which an upright bar or handle, j, is litted. Around the edges of thesides h h there are slats k, the ends ofthe latter being tted inrecesses in thc sides h, the slats projecting beyond the, sides androunded and covered with zinc, Z.

To the upper slat.- k, at one side of the concave C, there is attacheda` stationary handrubber, E, which is designed for rubbing such portionsof the clothes which the machine will not fully cleanse. The rubber D isprovided at each side with journals m, which are fitted in metalbearings un, the latter being inserted in grooves made in the upperedges ofthe sides b b of the suds box A. These bearings n may be cast inproper form. The clothes, it will be seen, are subjected to thenecessary pressure an-d rubbing between the rubber D and the concave C,the zinc-covered slats 7c and bars d acting upon the clothes, while thenotches or openings g admit of the suds passing through the concave andthe dirt settling on the bottom (t. The zinc covering ot' the slats 7cand bars d prevents the clothes being injured or torn, while it addsgreatly to the durability of the machine. The metal bearings n n alsoprevent wear.

I do not claim, broadly, a zinc bottom for a washing-machine; but

I do claim as new and desire to secure Letters Patent- The concave U,composed ofa seriesof alternate bars, d, and slats c, the former beingcovered with zinc,f, and the bars and slats fitted at their ends insemicircular grooves c, made in the inner surfaces of the sides b b ofthe suds box, in combination witha rubber,

D, provided with slats lc, with or Without a zinc covering. I,substantia'ly as and for the purpose set forth.
